We review the supersymmetric AdS 4 × w ℳ 6 backgrounds of type IIA/IIB supergravity constructed in [1]. In type IIA the supersymmetry is = 2, and the six‐dimensional internal space is locally an S 2 bundle over a four‐dimensional Kähler‐Einstein base; in IIB the internal space is the direct product of a circle and a five‐dimensional squashed Sasaki‐Einstein manifold. These backgrounds do not contain any sources, all fluxes (including the Romans mass in IIA) are generally non‐zero, and the dilaton and warp factor are non‐constant. The IIA solutions include the massive deformations of the IIA reduction of the eleven‐dimensional AdS 4 × Y p,q solutions, and had been predicted to exist on the basis of the AdS 4 /CFT 3 correspondence.
